Rent the Runway turned designer dresses into 4-day rentals for $150.

In 2009, renting clothes was not yet mainstream consumption; designer dresses often cost over $1,000, while data showed about half of the new clothes women bought were worn only once; two HBS students wanted to change the “closet” from purchasing to borrowing per use.

Change fashion to borrowing: rent dresses like Netflix rents DVDs, 4–8-day cycles, prepaid return, with dry cleaning and sizing coordinated by algorithms.

Partnered with designers to stock inventory, and the website rented dresses in 4-day or 8-day cycles (a 4-day rental cost about $150, while buying the same dress cost over $1,000); return using prepaid postage mail bags, with dry cleaning centralized at the company; self-developed algorithms scheduled 65,000+ (6.5万+) dresses and 25,000+ (2.5万+) accessories, predicted demand by event type, and on average each dress was worn by 30 customers.

Turned “renting dresses” from a taboo into a mainstream option: a 2016 Harvard case said the company used self-developed algorithms to manage 65,000+ (6.5万+) dresses and “turned the fashion industry upside down”; later added the Unlimited subscription, opened its first office outside the United States in 2019, and in 2021 became the first listed company led by female founders serving as CEO/COO/CFO.

In 2009, renting a designer dress barely existed in mainstream consumption. Harvard Business School students Jennifer Hyman and Jennifer Fleiss founded Rent the Runway, betting on another set of data: women buy an average of 64 new clothes a year, half of which are worn only once — what they wanted was the opportunity to “wear,” not the garment itself.

The model borrowed from Netflix: dresses were rented for 4 or 8 days, a 4-day rental cost about $150, while buying the same dress cost over $1,000; dresses were delivered to the door and returned using a prepaid mail bag, with dry cleaning centrally handled by the company. The company also partnered with designers, turning inventory into a channel for brands to reach new customer groups.

Operations were the heaviest and hardest part of this model: self-developed algorithms scheduled among 65,000+ (6.5万+) dresses and 25,000+ (2.5万+) accessories, predicted demand by event type, and on average each dress was worn by 30 customers. A 2016 Harvard case called it “turning the fashion industry upside down” — a fashion company whose core asset was an inventory algorithm.

Splitting a purchase of over $1,000 into a $150 use removed the price threshold directly, expanding the market from “can afford to buy” to “can afford to rent.”

A dress was rented about 30 times, earning from utilization rather than a one-time markup — the business model was built on repeated use.

Prepaid mail bags plus central dry cleaning turned the customer’s two major frictions (cleaning, return) into the company’s infrastructure.

Event data drove scheduling: which dress was rented for which occasion directly determined procurement, cleaning, and shipping priority.

When customers need only use, sell use: splitting price from $1,000 to $150 enlarged the market; heavy operations like cleaning and sizing are the moat.

Rent the Runway expanded from dresses to everyday clothing, accessories, and the “Unlimited” subscription, opened its first physical store in 2014, and in 2019 opened its first office outside the United States in Galway, Ireland; it listed in 2021, becoming the first U.S. listed company led by female founders serving as CEO, COO, and CFO. The pandemic severely hit event dress rentals, and the company later shifted toward secondhand and resale, with its official positioning expanding from a “clothing rental platform” to “the starting point of a circular fashion economy.”
